Ukrainian opposition leader Vitaly Klitschko has been booed by anti-government protesters in Kiev's Independence Square, hours after signing a deal with President Viktor Yakukovych aimed at ending the country's political crisis.

The agreement means a presidential election would be called earlier than planned, by the end of 2014.

However one activist from the Right Sector, a radical group, took to the stage to demand that Mr Yanukovych resign even earlier - by 10:00 local time (08:00 GMT) on Saturday.
